Abstract
The utility model discloses an expansion device for a conveying chain. The expansion device comprises a balance weight positioning frame, a balance weight block frame, a moving pulley, a guide wheel and at least one balance weight block, wherein sliding chutes are respectively formed on the left and the right of the inner side of the balance weight positioning frame; pulleys are respectively arranged on the left and the right of the balance weight block frame, matched with the sliding chutes and movably arranged in the balance weight positioning frame; the moving pulley is connected to the inner side of the balance weight block frame through a rotating shaft; a hanging rod is arranged at the bottom of the balance weight block frame; each balance weight block is sleeved on the hanging rod; and the guide wheel is independently arranged on the upper part on one side of the moving pulley. The expansion device has the advantages of long expansion distance, stable performance, low fault rate and long service life.
Description
Technical field
The utility model relates to a kind of conveyer chain swelling device, relates in particular to a kind of swelling device of high temperature conveyer chain.
Background technology
With regard to high temperature conveyer chain swelling device, domestic existing mechanical screw mandrel and the spring swelling structure of all adopting, promptly the end at conveyer chain is equipped with the adjusting screw mandrel, and the adjusting through screw mandrel comes the swelling chain; Perhaps adopt the swelling spring, at high temperature the expanded by heating overtime can be through the elastic force swelling chain of spring when conveyer chain.The high temperature conveyer chain swelling device swelling distance that adopts mechanical screw structure to make is little, and fault rate is high, and service life is short; The high temperature conveyer chain swelling device that adopts spring structure to make, under the long-term work environment, the spring easy deformation, following the string does not have the purpose of swelling and causes chain sideslip and breaking phenomenon.
Summary of the invention
The technical matters that the utility model will solve is that existing swelling device is being carried under the chain length distance and the condition of high temperature; Can't regulate or be easy to generate distortion or swelling spring follows the string; And do not have the purpose of swelling, thereby cause chain sideslip or breaking phenomenon.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of conveyer chain swelling device comprises counterweight locating rack, clump weight frame, movable pulley, track adjusting wheel and clump weight; Be respectively equipped with chute about said counterweight locating rack inboard, establish pulley about the clump weight frame respectively, pulley and chute match to merge and are movably arranged in the counterweight locating rack; Said movable pulley is connected clump weight frame inboard through rotating shaft; The bottom of clump weight frame also is provided with suspension rod, and clump weight is enclosed within on the suspension rod, at least one of said clump weight; Said track adjusting wheel independently is arranged at the top of movable pulley one side.
During installation, make chain walk around the bottom of movable pulley and the top of track adjusting wheel, being equipped with of movable pulley and track adjusting wheel makes chain under the weight of clump weight, be in the state of tightening all the time; When chain was in cold conditions, the length of chain was former length, and this moment, pulley was in position last in the chute; When the chain expanded by heating, the length of chain is elongated, under the clump weight action of gravity; Pulley moves down along chute, thereby reaches the effect of the degree of tightness of automatically regulating chain, avoids occurring chain sideslip and breaking phenomenon; Improve the service life of conveyer chain, practiced thrift the use cost of conveyer chain.
As a kind of improvement project of the utility model, also be respectively equipped with the cooresponding mounting hole in a pair of position about said clump weight frame inboard, bearing installation is passed through in mounting hole in the two ends of the rotating shaft of movable pulley.
The utility model has the advantages that: swelling distance, stable performance, low, the long service life of fault rate.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 be Figure 1A-A to cutaway view.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Shown in Fig. 1-2, the utility model comprises counterweight locating rack 2, clump weight frame 4, movable pulley 3, track adjusting wheel 9 and clump weight 5; Be respectively equipped with chute 2-1 about said counterweight locating rack 2 inboards, clump weight frame about 4 is established pulley 4-1 respectively, and pulley 4-1 and chute 2-1 match to merge and be movably arranged in the counterweight locating rack 2; Also be respectively equipped with the cooresponding mounting hole in a pair of position about said clump weight frame 4 inboards, bearing installation is passed through in mounting hole in the two ends of the rotating shaft of movable pulley 3; The bottom of clump weight frame 4 also is provided with suspension rod 8, and clump weight 5 is enclosed within on the suspension rod 8, and the quantity of said clump weight 5 is to be equipped with at least one according to the degree of tightness of chain; Said track adjusting wheel 9 independently is arranged at the top of movable pulley 3 one sides.
During work, workpiece 7 lies on two parallel conveyer chains 1, and every conveyer chain 1 lower end is equipped with a swelling device; Drive wheel 6 drives conveyer chain 1 operation, utilizes the weight of clump weight 5 to make conveyer chain 1 be in the state of tightening all the time, when conveyer chain 1 is in cold conditions; The length of chain is former length, and this moment, pulley 4-1 was in position last among the chute 2-1, when conveyer chain 1 expanded by heating; The length of chain is elongated; Under clump weight 5 actions of gravity, pulley 4-1 moves down along chute 2-1, thereby reaches the effect of the degree of tightness of automatically regulating chain.
